Light weight appliance to be used with smart devices to produce shortwave infrared emission

Abstract

A short wavelength infrared (SWIR) energy emitting unit, and device having a SWIR emitting unit, for producing SWIR energy from an emission source emitting electromagnetic energy. The SWIR energy unit comprises a phosphor material, an electromagnetic energy blocking member, a substrate for delivering the system or material to an electromagnetic energy emission source, and optionally, an attachment member.

What is claimed is: 
     
       1. A short-wavelength infrared energy producing unit configured to affix to a device capable of emitting at least one source of electromagnetic energy comprising:
 a substrate material securable to said device capable of emitting at least one source of electromagnetic energy through a frictional fit attachment member comprising a plurality of walls formed together to partially enclose an interior region, said interior region sized and shaped to receive or engage with at least a portion of a device having a source for emitting ultraviolet or visible light; 
 a phosphor layer; and 
 an electromagnetic energy blocking layer; 
 said frictional fit attachment member comprises an opening of sufficient size to allow emission of electromagnetic energy from said at least one source of electromagnetic energy on one first, front wall and said phosphor layer and said electromagnetic energy blocking layer positioned on an opposite, second, back wall. 
 
     
     
       2. The short-wavelength infrared energy producing unit configured to affix to a device capable of emitting at least one source of electromagnetic energy according to  claim 1 , further including an attachment member. 
     
     
       3. The short-wavelength infrared energy producing unit configured to affix to a device capable of emitting at least one source of electromagnetic energy according to  claim 2 , wherein said attachment member includes a pressure sensitive adhesive. 
     
     
       4. The device for producing short-wavelength infrared emissions according to  claim 1 , further including a protective shield. 
     
     
       5. The device for producing short-wavelength infrared emissions according to  claim 4 , wherein said protective shield is made of an optically transmissive material. 
     
     
       6. The short-wavelength infrared energy producing unit according to  claim 1 , wherein said phosphor is contained in a binder or carrier. 
     
     
       7. The short-wavelength infrared energy producing unit according to  claim 1 , wherein said electromagnetic energy blocking layer is one or more wavelength-blocking optical filters configured to at least partially block emissions of NIR light, visible light, or combinations thereof. 
     
     
       8. The device for producing short-wavelength infrared emissions according to  claim 1 , wherein said electromagnetic energy blocking layer is a NIR or visible light filter configured to render said device capable of emitting at least one source of electromagnetic energy invisible to a NIR or visible light detection system or sensor.
